1 Claim. (01. 214-140) An important object of the invention is to provide a rake attachment which may be readily and easily secured to the free ends of the swinging supporting arms of loaders, in lieu of the usual scoop, the operation of the rake permitting use of the usual loader attachments for loading or handling hay, straw, or like material.

Another important object of the invention is to provide an attachment of this character which may be readily and easily mounted upon removal of the scoop of the usual loading device and one wherein the movements of the rake will be cushioned to relieve the swinging arms of the load ing mechanism of undue strain.

A further object of the invention is to provide means for tilting the rake proper to prevent the load lifted by the rake from sliding therefrom.

Still another object of the invention is to provide means for releasing the rake for forward pivotal movement so that the rake may assume a position for moving under its load.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and'combinations of parts here- 4 inafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a perspective view illustrating a tractor equipped with a conventional loading attachment, the rake forming the subject matter of the present invention being supported on the swinging arms of the loader.

Fig. 2 is a side elevational view of the attachment, the boom to which the attachment is secured, being indicated in dotted lines.

Fig. 3 is a perspective view of one of the attaching arms for attaching the rake.

Fig. 4 is a fragmental perspective view illustrating the means for restricting movement of the rake frame with respect to the boom arms.

Fig. 5 is a front elevational view of the attachment.

Fig. 6 is an enlarged view partly in section illustrating the latch control means controlling the telescoping of the side bars of the attachment.

Fig. 7 is a sectional view illustrating the yieldable means employed in connecting the control rods of the attachment, to the, rake frame.

Referring to the drawings in detail, the reference character 5 indicates the conventional tractor to which the loader frame 6 is pivotally connected, the loader frame embodying the usual boom 1 which includes pivoted arms 3 that extend forwardly beyond the front end of the tractor, as clearly shown by Fig. 1 of the drawings.

The rake attachment, forming the subject matter of the present invention, includes rear spaced bars 9 that have pivotal connection with the tractor, through the bars Hi, forming a part of the loader attachment to which the rake attachment is connected.

- Pivotally connected with the loader attachment, are upstanding bars II to which the forward ends of the bars 9 are pivotally connected, the connection between the bars 9 and II being spaced from the upper or free ends of the bars I I.

The side bars of the rake attachment embody telescoping sections I2 and I3, the sections it moving into the hollow sections I2 which are pivotally connected with the upstanding bars I I, at the upper ends of the bars II, the forward ends of the sections I2 extending to points adjacentto the rake frame I4. The sections it which extend into the hollow sections I2, are formed with notches I5 adjacent to their inner ends, the notches being so arranged in the sections I3 that they will fall opposite to the slots I6 formed in the sections I2 where the notches are engaged by the right angled ends ll of the rod I8 that is pivotally mounted in bearings It supported on the sections I2. A cross arm indicated at 20 is secured to the rod It, to the upper end of which is connected the spring 2i, the opposite end of the spring 2| being secured to the section I2 at 22, with the result that nor mally the cross arm 21 is urged towards the pivoted end of the section l2 which causes the ends H, which provide latches, to move into contact with the section I3, as it moves through the section l2. It is obvious that when the section 13 moves to the position as shown by Fig. 6, the latches or right-angled ends I'i, will move into the notches I5 holding the sections i2 and I3 together.

As clearly shown by the drawings, the cross arm 20 extends a distance below the rod I8 and is provided with an eye through which one end of the operating cable 23 extends, the opposite end of the cable 23 being disposed in proximity to the operators seat, so that the cable may be 3 pulled to move the latch H to disengage the section I3, allowing the section 13 to slide within the section l2.

The rake head or tine includes a rake frame comprising upstanding bars 24 secured in spaced relation with respect to each other by the horizontal bars 25. Adjacent to the center of the rake head or tine frame, are upstanding bars 26 that are also connected with the bars 25. These bars 2.6 are formed with vertically elongated openings 21 through which the forward ends of the sections it extend, the sections 13 having discs 28 secured at their forward ends against which the springs 29 rest, the opposite ends of the springs 29 engaging the discs 3 on which the rubber cushioning blocks 3t rest; the cushioning blocks 3| engagingthe bars 26. adjacent to the openings 21, cushioning movements of the lift bars of the rake attachment, which include sections [2 and [4.

The rake head or tine frame also embodieslongitud-inallyspaced horizontal. bars 32 and 33,- there being provided brackets 34 rising from the ends of the bar 33, to which the upper tines 35 of the rake are secured, the tines 36. which, also form a part of the rake, being horizontally dis-- posed and are secured to the horizontal. bars 32 and 33 from. which they extend iorwardlras. clearly shown by Fig. 1. of thedrawings.

The rake head or tine frame; is provided. w t ready attaching slip on brackets 31., each; of whichv embodies arms. 38 secured. together at, their forward ends, while the rear ends thereof are spaced apart. andconnected with the. yoke 39,, the yoke of the. brackets 31. bein elon d. in be fitted over the forward, ends. 011 the pivoted, arms. 8 of the boom of the loader to which. the device is attached, the. yokeshatin D v-total, con nection with the arms 8. at 40;.. The, arm 33: have their forward ends disposed at. acuteangles, with respect to the yokes it so that they at under the. bars 32-. and 33 where they are p votal-11y. 0 nected with the bar 33 at 4.1.. Secured. to inter.-

mediate tines oi the. rake, are arms 42, which arms extend upwardly. from the tines, and, then. downwardly to engage: the. brackets 31, Rods, 43 are secured to;- tines. adjacent. to the tines on which the. arms 42 are secured andextendu e wardly through elongated open n s. the arms 42, there. being provided coiled, springs M resting; a

on the, arms. 42. with their upper. ends. en the. discs 4.5 secured on the: upper ends. of. the;

4 rods 43. Thus it will be seen that due to this construction, upward tilting movement of the tines of the rake will be restricted, and the tines will be held in contact with the ground.

From the foregoing it will be seen that due to the construction shown and described, I have provided a rake attachment which may be readily and easily attached to the boom of the usual loader attachment for tractors, in lieu. of the usual scoop of the loader, converting the attachment into a means for loading hay, straw or the like, material.

It will also be seen that due to the construction the operator of the tractor will have control of the rake at all times, to cause the rake to pick up hay or straw, and dump the load at the desired location.

nected' to the boom oi the tractor and time fram adjacent to the lower edgethereoi, ayoke form inga art of each bracket, said yokesstraddling:

said booms beyond the pivot points between the brackets and boom, providing stops restricting: tilting movement of thetinetrame with respect to the boom, and yieldable means embodying:

" spring arms connected to certain or the tines bearing against the brackets tilting said tine frame and tines towards the ground.
